The Belgian participating broadcaster, Flemish Belgische Radio- en Televisieomroep (BRT), selected its entry through a national final.

Flemish broadcaster Belgische Radio- en Televisieomroep (BRT) competed in the Eurovision Song Contest 1987 for Belgium, while Walloon broadcaster Radio-télévision belge de la Communauté française (RTBF) hosted the event due to them winning the previous year.

The twelve chosen artists were: Daan Van Den Durpel, Angie Dylan, Margriet Hermans, Bart Kaëll, Curt Lawrence, Dan O'Neil, Sonia Pelgrims, Sofie, Liliane Saint-Pierre, John Terra, Vincent, and Judith Vindevogel.
